Abstract: 211,927. Thornycroft & Co., Ltd., J. I., and Thornycroft, Sir J. I. Nov. 23, 1922. Driving-arrangements for screw propellers.- The shaft or shafts of semi-submerged propellers are arranged at such an angle to the centre-line of the vessel that the mean section of each propeller blade on immersion will be at right-angles to the centre and so drive the water directly astern. In one form the propeller b is mounted on a shaft inclined as to fulfil the required condition and when the latter is connected bv belt or toothed gearing with the engine g the whole. arrangement is balanced as regards weight with respect to the centre line of the ship. The balance of the arrangement may also be effected, where the propeller shaft is driven direct from the driving shaft, by suitably disposing the condenser on the opposite side of the centre line. In another arrangement, two propeller shafts are inclined in opposite, directions to the centre line of the ship and cross on the centre line.

Title: Manufacture of resin-impregnated paper
IPC: D21H17/19
Filed: 1971-07-09
Abstract: 1350668 Resin impregnated paper laminates OTSUKA KAGAKU YAKUHIN KK 9 July 1971 [10 July 1970] 32262/71 Heading B5N [Also in Divisions D2 and C3] A process for producing resin impregnated paper products by impregnating paper with a polymerizable substance, a free-radical initiator and a polymerization accelerator and heating or irradiating with ionizing radiation to produce polymerization, is characterized by the fact that the paper is impregnated with the three components prior to polymerization, in two or three stages in each of which one or two of the components are present separately from the other component or components, the polymerizable substance being a vinyl or vinylidene monomer or an oligomer thereof, or an unsaturated polyester dissolved in a vinyl or vinylidene monomer. The amount of accelerator present is sufficient to ensure complete polymerization. In the examples, corrugated paper comprising a sheet of corrugated paper sandwiched between two flat sheets of paper is used. In Example (2) an impregnated laminate of 5 sheets of such paper was produced by (a) impregnating each with a solution of cumene hydroperoxide and cyclohexanone peroxide (initiators) in methanol (the methanol then being evaporated), (b) superposing the sheets and impregnating with a mixture of styrene, methyl methacrylate and azodiisobutyronitrile (monomers and foaming agent) and (c) impregnating with cobalt naphthenate (accelerator) dissolved in styrene. The assembly was then cured with heat, to produce a foamed structure. In Example (3) a laminate of two sheets of the same corrugated paper impregnated with a vinyl acetate/methmethacrylate copolymer was produced in a similar manner, except that it was not foamed.

Title: Improved method of separating and recovering gases and apparatus therefor
IPC: B01D53/04
Filed: 1919-12-24
Abstract: 137,284. Patrick, W. A., Lovelace, B. F., and Miller, E. B. Dec. 28, 1918, [Convention date]. Drawings to Specification. Volatile solvents, recovering.-Vapours of volatile solvents such as alcohol. ether, acetone, carbon disulphide, chloroform and gasoline are separated and recovered from mixtures containing them by absorption in a porous body such as hydrated silicon dioxide gel, and afterwards liberating the absorbed constituent from the porous body; a necessary condition is that the pores of the latter must be of such a size as to give a vapour pressure of water at 15‹ C. of 3-11 m.m. (mercury), and they are then sufficiently small to ensure effective absorption but not so small as to inhibit or render difficult the liberation of the desired constituent. Liberation of the gas or vapour is effected by disturbing the equilibrium conditions between the gas absorbed in the gel and the gas exterior thereto, for example by passing a current of air over the absorbent material, or by raising the temperature, or by lowering the pressure, or by a combination of these methods. In some cases, in order to facilitate absorption, the gas &c. mixture may be cooled; but it is practicable to effect the separation at a temperature up to about 50‹ C. above the boiling-point of the desired constituent. The hydrated silicon dioxide gel is prepared by the coagulation of a colloidal solution of silicic acid as described in Specification 136,543, [Class 1 (l), Chemical processes &c.], and is afterwards washed and dried so as to give a product containing a small amount of water of hydration; but gels of alumina and ferric or stannic oxides may be employed. The process is applicable to the recovery of sulphur dioxide, carbon dioxide, nitrogen oxides, ammonia, alcohol, ether, acetone, carbon disulphide, chloroform, and gasolene. Specification 7808/05, [Class 1. Acids, alkalies, &c.], is referred to.
